There are a quadrillion startups (mem0, langmem, zep, supermemory), open source repos (claude-mem, beads), and tools that do this.
My approach is literally just a top-level, local, git version controlled memory system with 3 commands:
- /handoff - End of session, capture into an inbox.md
- /sync - Route inbox.md to custom organised markdown files
- /engineering (or /projects, /tasks, /research) - Load context into next session
I didn't want a database or an MCP server or embeddings or auto-indexing when I can build something frictionless that works with git and markdown.
